Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1 to Figure 3, the gathering propulsion plant of the bar-shaped powder stick of the present embodiment, including frame 1, a plurality of guiding for being drawn in by multiple powder sticks draws groove 2 and the propelling movement assembly being located in frame 1 in, a plurality of guiding is drawn groove 2 in and is arranged in frame 1 and is in same level, the entrance point that all guiding draw groove 2 in is positioned at the side of frame 1, the port of export is positioned at the opposite side of frame 1, and all guiding draws the horizontal spacing between groove 2 port of export in less than the horizontal spacing between entrance point, multiple powder stick so can be made to move closer to draw in the process drawing groove 2 conveying along guiding in.Push assembly and include powder stick pushing plate 3, crank yaw link mechanism 4 and the rotary drive 5 being connected with crank yaw link mechanism 4, powder stick pushing plate 3 is positioned at a plurality of guiding and draws the top of groove 2 in, crank yaw link mechanism 4 is connected with powder stick pushing plate 3 and orders about powder stick pushing plate 3 annularly track and draws shuttling movement between entrance point and the port of export of groove 2 in guiding, the entrance point that annular trace includes powder stick draws groove 2 in from guiding pushes to the horizontal rectilinear motion track A of the port of export and is back to the return movement locus B of the port of export from the entrance point drawing groove 2 in that leads, return movement locus B is positioned at the top of horizontal rectilinear motion track A.
In the present embodiment, crank yaw link mechanism 4 includes horizontal mounting plate 40, first crank 41, second crank 42, first long rocking bar 43, second long rocking bar 44, first short rocking bar 45 and the second short rocking bar 46, first crank 41 and the second crank 42 are installed in frame 1 respectively through rotating axle, the two ends of the first long rocking bar 43 are hingedly connected on the first crank 41 and horizontal mounting plate 40, the two ends of the second long rocking bar 44 are hingedly connected on the second crank 42 and horizontal mounting plate 40, the two ends of the first short rocking bar 45 are hingedly connected in middle part and the frame 1 of the first long rocking bar 43, the two ends of the second short rocking bar 46 are hingedly connected in middle part and the frame 1 of the second long rocking bar 44, the drive end of rotary drive 5 and the rotation axle of the first crank 41 are connected, it is hingedly connected with synchronising (connecting) rod 47 between first crank 41 and the second crank 42, the two ends of synchronising (connecting) rod 47 are hinged with the first crank 41 and the second crank 42 respectively, make the first crank 41 and the second crank 42 synchronous axial system. powder stick pushing plate 3 is connected to the lower surface of horizontal mounting plate 40, and powder stick pushing plate 3 promotes and contacts with the tail end of powder stick during powder stick.
Rotary drive 5 orders about the first crank 41 and rotates, second crank 42 is with the first crank 41 synchronous axial system, under the restriction effect of the first short rocking bar 45 and the second short rocking bar 46, first crank 41 and the second crank 42 rotate in the process of a week, first long rocking bar 43 and the second long rocking bar 44 first make horizontal mounting plate 40 move to the port of export with powder stick pushing plate 3 along the horizontal rectilinear motion track A entrance point drawing groove 2 in from guiding, then make horizontal mounting plate 40 return to the entrance point of guiding gathering groove 2 along parabolic return movement locus B with powder stick pushing plate 3. First crank 41 and the second crank 42 rotate in the process of a week, and the movement locus of powder stick pushing plate 3 is as shown in Figure 4.
